ISL6326
4-Phase PWM Controller with 8-Bit DAC Code Capable of Precision DCR Differential Current Sensing
FN9262 Rev 1.00 May 5, 2008
The ISL6326 controls microprocessor core voltage regulation by driving up to 4 synchronous-rectified buck channels in parallel. Multiphase buck converter architecture uses interleaved timing to multiply channel ripple frequency and reduce input and output ripple currents. Lower ripple results in fewer components, lower component cost, reduced power dissipation, and smaller implementation area.
Microprocessor loads can generate load transients with extremely fast edge rates.
